Here’s a shot of the new 3900T Manitowoc truck crane lifting the front end of an old gas electric car for maintenance on the power truck. The 3900T first appeared in 1963 and was the biggest of its type at the time. I recently built this and rigged it with a 60 ton block and an eight part line. It is show here working with a 60 foot basic boom at about a 28 foot radius. In this position it can safely lift 50 tons with the spreader bar although lifting the heavy end of the car is should be within 40 tons.
More pictures will posted soon making other heavy picks.
